Jonathan Posner joins Mechanical Engineering from Arizona State University, where he was an associate professor in mechanical and chemical engineering as well as an adjunct professor in the Consortium for Science, Policy & Outcomes. Formerly he was a postdoctoral scholar at Stanford University.

His research focuses on micron- and nanometer-length scale fluid dynamics and transport physics at the interface of chemistry, biology, and the environment. His work enables novel technologies in electrokinetic systems, including new behaviors in non-dilute colloidal suspensions, applicable to the electrophoretic deposition of colloidal crystal films; as well as providing new functions and understanding of engineered nanoparticles that swim by harvesting chemical energy from surrounding solution. His energy research includes the development of membrane-less fuel cells to power portable electronics and autonomous systems. He also studies the environmental and health impacts of engineered nanoparticles, as well as the regulation and ethics of nanotechnology.

Professor Posner’s honors include a NSF Career Award, an APS Division of Fluid Dynamics, Gallery of Fluid Motion Award, an Arizona State University Mentor Award and a von Karman Institute award for Excellence in Experimental Research.
